DRAINAGE VALVE.

Application filed March 18, 1925.

To @ZZ whom t may concern:

Be it known that I, HERMAN MocKUs, a citizen ot the United States,residing at Chicago, in the county et Cook and State ot illinois, haveinvented new and useful lmprovements in Drainage Valves, ot which thefollowing is a. speciiication.

This invention relates to new and useful improvement-s in drainagevalves and more particularly to a. device of this character which isapplicable to drainage openings and the like which are usually placed inthe floors of basements, cellars, etc.

rlhe main object of my invention is the provision ot a drainage valvewhereby the same is so constructed as to be readily applied to the usualdrainage openings in basements and is normally in a closed position toprevent any backing of water from the sewer from entering the basementand which can be quickly and readily actuated when it is desired todrain any water from the basement floor.

Another object of my invention is the provision of a drainage valveincluding suitable means for normally retaining the valve in a closedposition with additional means whereby the same may be manuallymanipulated for operating the valve to permit drainage thru the drainpipe to which the valve is attached.

A further object ot my invention is the provision of a drainage valvewherein the operating parts thereof are within the usual concreteiooring in basements and the like so as to prevent articles from beingbrought into contact with the working parts whereby the valve will beready for operation at all times.

With the above and other objects in view, the invention consists in thenovel features of construction, the combination and arrangement of partshereinafter more fully set forth, pointed out in the claims and shown inthe accompanying drawings, in which:

Fig. 1 is a top plan View of the drainage valve constructed inaccordance with my invention, parts thereof being broken away andillustrated in section,

Fig. 2 is a longitudinal sectional view, and

Fig. 3 is a detail transverse section on the line 3 3 of Fig. l.

Referring more particularly to the drawings, the numeral 1 indicates adrainage pipe leading to weil-known drainage system Serial No. 16,496.

and attached to the upper end ot this pipe is a catch basin 2, having a.perforated plate 3 arranged horizontally against the hasement adjacentthe upper end thereot. This basin is usually set inte the concreteflooringet' a` basement and generally at a low spot whereoy any water onthe iioor ot' the basenient will readily run toward the base 2. ris thiscatch basin 2 normally remains in an open position, the water from thesewer has a. tendency to back thru the same into the basement ot. thebuilding and in order to prevent this backing of the water, I haveconstructed a novel 'term ot valve which normally closes thecommunication to the sewer and prevents any backing of water therein.

Suitable housings 5 and 6 are arranged adjacent the basin 2, saidhousings being preferably in spaced relation as shown in 2 andconnecting the housings is a .sl-.neve .7,

lsl'ovable thru the housings 5 and G and the sleeve 7 is an operatingshaft 8.' the inner end ot which is connected as at 9 to a perforatedvalve plate 10. The plate l0 is mounted within the suitable opposedguides 11 connected to opposite sides ot the basin 2.

The shaft S is provided adjacent its inner end with a head 12 whichnormally hears againsta shoulder 13 in the housing 5. Disposed betweenthe head 12 and the outer wall of the basin 2 is a. coil spring 14:which normally retains the shaft 8 in an outward position with the hea-d12, bearing against a shoulder 13. This position retains theperiorations in the valve plate out ol' alignment with the pertorationsin the plate 3. h

The housing 6 has extended outwardly therefrom a shaft 15, having a handwheel 16 upon its outer end and a c ank arm 17 at its inner end which isarranged within the housing. The c'ank arm 17 is connected to the outerend of the shaft 8 by means of a link 18 whereby it will be noted thatwhen the shaft is rotated, turning the handle wheel 16 to the right, theshaft S will he reciprocated inwardly toward the catch basin 2compressing the spring 14 and moving the valve plate 10 so that thepertorations therein will be brought into alignment with theperforations in the plate 3, permitting any water standing above the.catch basin to be drained therethru,

In order to provide for proper alignment for the perforations in theplates 3. and 10, a stop pin 19 is carried by the shaft 8 and is adaptedto engage with the shoulder 13 in order to limit the movement of theshaft 8 upon itsinward stroke, thus as the pin 19 strikes the shoulder,the plate 10 will have been moved a suiiicient distance to bring theperforations therein into alignment with the perforations in the plate3.

It will be apparent from the'foregoing that when the hand wheel isreleased after completely draining` the water thru the basin, thetension of the spring 111- will return the shaft 8 to its normalposition, closing the openings between the plates 3 and 10 whereby thedrainage valve will always remain in a normally closed position toprevent any baclr-ingof the water from the sewer thru the drain into thebuilding.

As noted the several parts o-f the device are embedded or arrangedbeneath the surface of the cement licor whereby they will be entirelyout of the way and the hand wheel 16 may be located at one side of thebasement and the shaft 8 connected thereto in any suitable mannen WhileI have shown and described the preferred embodiment of my invention, itwill be understood that various changes and alterations may-be madewithout departing from' the spirit of the invention or the scope of theappended claims.

Having thus descr-ibed'my invention, what claim is: l

l. In combination with a catch basin having a stationary perforatedplate therein, a movable perforated plate upon one side of' thestationary plate, a housing adjacent the 2. The combination with a drainopening having a perforated plate against the same, of a movable valveplate disposed beneath the first plate and having openings-therethru, alongitudinally movable shaft having one end connected to the valveplate, manu-- ally operated means connected toY the other end of theshaft, a head portion on the shaft,

a spring normally bearing against: the head for moving the shaft in onedirection, a stop,

shoulder adapted to be engaged by the head to h mit the movement of theshaft, a pin carried by the shaft in spaced relation Vwith the head forengagingtjhe stop shoulder upon,

the opposite side to limit the movement of f the shaft in the oppositedirection whereby the openings .in the valve plate mayVr be aligned withthe perforations'in'the drain plate against the tension of the springthruthe manually operated means and the tension of saidspringreciprocatingthe shaft in the opposite direction to move theopenings in the valve plate out of alignment with the openings inthedrainv'plat'e. Y.

In testimony whereof I afiiX my signature.
